Abstract

<p>  Walker and rollator are often confused because of their similar shapes, they require different operating abilities due to their structural characteristics. This study aimed to clarify the relationship between the walking aids and the movement of the trunk, and the difference in the movement of the upper limbs in the directional change operation using a walker and a rollator. The subjects were 19 healthy young people, and the task consisted in changing directions by 90 degrees using a walker and a rollator. Using a three-dimensional motion analysis system, we calculated the relative rotation angles between the thorax and pelvis, between the walking aids and thorax, and between the walking aids and pelvis, the trunk flexion angle, and the upper limbs angle are compared the differences between the walker and the rollator. The relative rotation angle between the thorax and pelvis, between the walking aids and the thorax, and between the walking aids and the pelvis, and the time to change direction were significantly increased in the walker compared with the rollator. In both cases, the trunk was flexed. The walker increased the elbow joint flexion on the side of the directional change, and the rollator increased the shoulder joint flexion on the opposite side of the directional change. It was suggested that the walker changed directions while rotating and the rollator changed directions while pushing. When prescribing or practicing walking aids, it is necessary to consider these characteristics according to the user.</p>
